I have a number of questions regarding product import in Magento.
In dataflow profile:
How come I get an error that says the image does not exist if I try to change the SKU value of the product on the exported csv file and try to import it back? This error does not appear if I keep the value of the SKU as is. Is the product considered by Magento as a new product if you modify the SKU so it can't find the existing image?
Why isn't the product showing on my catalog in admin and frontend even though I got the notice that the record was successfully imported? I tried changing the name of one product on the csv and imported it thinking that it might have just overridden the existing product on the website but this doesn't seem to be the case as the product was not updated.
Additional Note: I've made sure to clear cache and reindex data after the import. Also, whenever I tried to import the image to /media/import even though it already exists in /media/catalog/product/folder/file.jpg when I change the SKU, the import seems to work fine.
